ABSTRACT

Objective To localize the upper airway obstruction of patients with obstructive sleep apnea hypopnea syndrome (OSAHS)with the Cinema Magnetic Resonance(Cine-MR) and fiber optic laryngoscope with Müller maneuver(FLMM)before operation and discuss the clinical application values.Methods Before operation, FLMM and Cine-MR were applied to 22 patients diagnosed as OSAHS by Polysomnography(PSG).Medical examinations conducted in this study from September 2015 to April 2016 to examine the obstruction of the soft palate region, the lingual region and epiglottis.Results There were complete agreements between the Cine-MR and FLMM at locating obstruction sites of the soft palate (n=22/n=22),and there were moderate agreements between the Cine-MR and FLMM in locating obstruction sites of the retroglottal region(n=13/n=6),epiglottal region (n=4/n=2)and multiple level(n=13/n=6), respectively.Conclusion For those moderate and severe OSAHS patients with multiple sites obstruction , the preoperative application of the Cine-MR and FLMM together will be better in locating the obstruction sites.
